Rails - Nov 2009 - Problem creating Email form with redirect back if there are errors

Newbie here. I''m trying to create a simple e-mail form that validates
if the name & email have been entered, and if not, sends the user back
to the form with the previously entered data. The problem is I''m
losing the form parameters (param[:name], param[:address], param
[:message]), which means the user will have to re-enter them. What am
I not understanding?

  def deliver_email
    @errors = []
    if params[:name].empty?
        @errors << "Enter your name"
    end
    if params[:address].empty?
        @errors << "Enter your e-mail address"
    end
    unless @errors.empty?
        flash[:notice] = @errors
        redirect_to (:action => ''compose_email'', :id =>
params[:id])
    end
(send the email...)
  end

So there are a few ways to do this, but since you are a newbie, it might be
best to use a model, rather than parameters ("Rails way" vs. "You
could do
it like that").  To fully diagnose this issue, I need to see the view.  My
guess is that you are not including the params in the view to populate the
form.
